Serial Iihis invention relates to appl iances used for producing a -so-ca l led penmanent wave and the mainobjectof the inventionis to provide a novel means tor insulating the :end of the permanent wave curling mod w hich is adjacent the scalp-so as to prove t the possibility of the customer becoming bu-r-ne'd by contact'o f the-hotro'd with' the scalp.

In order to give an understanding o'f' the invention 1 have illustr ated in" the drawings some selected embodiments the-reof which will now be described -a 'fter which the novel teatures-w ill be pointed out the appended claims.

n Fig. 1 is a view illustrating a single permanerrt wa-ve curling rod with the lock 0t hair wound thereon-and having any shield applied thereto Fi g. '2 is aperspective view of one form of shield member;

Fig. 3 is p'erspeefi ve'v iew of a di-fierent tor-m er shield member igsme and "5* showthemanner in "which theshield member shown F'igfi3 is applied tothe curling rod, beinga section at rightan-"glestoFig'A.

in making a permanent waved wisp or lock of hair is wound tightly on acun ing rod and -then a prepared pad is placed around the curl and clamped thereto after which the heating unit is applied to the exterior of the pad for producing the desired curl in the hair. During this operation the end of the rod which is adjacent the scalp is exposed and it is necessary to use considerable care to prevent this exposed end of the rod which becomes quite hot from contacting with the scalp and thus producing a burn.

My improvements provide a novel protector or shield which encloses the exposed end of the rod and gives this desired protection.

In the drawings I have shown a single permanent wave curling rod and its associated pad and electric heater but it will be understood, of course, that in making a permanent wave a number of these curling irons are used.

1 indicates one of these permanent wave curling rods about which is Wound a lock 2 we of hair, the lock of hair being tied to the end of the rod by a suitable string 8 and the ends 0% the string being caught in the slit 4 with which these curling rods are usually pro added.

*5 indicates the usual pad which is placed 65 around the lock or curl :of hair after it is wound'on the rod 1 and :6 indicates the usual clamp employed torclamping the end of the pad tightly about the curl 2. 7 indicates the usua'lelectric heating device which encloses 60 the pad and which supplies the heat necessary for producing the desired permanent wave effect.

"-Dhe pants thus tardescribedare such asare usually found in permanent wave appliances 05 and term no partof present invention.

applying the curl or-lock 20f hair to the rod 1 it is customary to begin the winding asl-ight distance from the end 8 of the rod so that the slit end of the rod will be exposed beyond the end of the string 3. This exposed end of the rod becomes quite hot and unless great care is used it is apt to come in contact with the scalp and-cause a burn.

As stated above my improvements relate 75 to means tor protecting the heated end 8 of the rod 1 so as to prevent it from contacting with the scalp. One form of protector or shieid adapted for this pur pose is indicated at Sand-is shown in Fig. 2. This protector 9 B0 is a two-part member comprising the two parts iO-and 11. The part 10 is provided with asoc'ket portion 12- adapted to receive the end 8 ef-the -rod and=with a flange portion 18, which; however, does not-extend clear around the socket member T2. The member 11 is shown as pivoted to the flange 13 as indicated at 14=and said member is formed on one edge with'the notch-15 adapted to embrace the rod when the *two parts are olosedand are in operative position. This protector will be made of some suitable heat-insulating material, such-tor instance as fibre or hard rubber.

In using the device thelock or curl of hair is=-wound-onthe curling rod and the pad is i applied and clamped in position in usual way. Afterthis is :done' the shield 9 may be ap- Th-is is done by opening the two :me1nbers of the shield-"as shown in Fig. 2 and then inserting the end 8 ot t'herod in the socket 309 section 11 interposed between-the'clamp 6and the head. All the exposed metal parts of the permanent wave appliance which areadja cent the scalp are thus protected thereby eliminating any danger that the scalp may become burnt.

In Figs. 3 and 4 I have shown somewhat '7 different embodiment of the invention. In this case the protector or'shield is in thefform of a tube 20 of heat-insulatingmaterial which is formed in one side with an opening 21 to receive the end 80f the rod, One side of the tube iscut away at 22 to form a throat leading to the opening 21. This form of insulator is-used by forcing the exposed end 80f the rod laterally through the throat 22 into the opening 21 so that the end or" the rod is located within the tube as shown in Fig. 4. The resiliency ofthe walls of the member 20 retains it on the rod.,

This protector or insulator will preferably be so applied to the rod that the extremity of therod will bespaced somewhat from the walls of the tube. The device thus serves to protect the end 8 of the rod 1 and prevent it from contacting with thescalp and since the protector is made ofheat-insulating mate- "rial it will not become hot enough to burn or injure the scalp. Both forms of my invention, therefore, provide protection against the burning of the scalp by contact therewith oi: the hot end 8 of the curling rod. I claim: 1. In a permanent wave appliance, the combination with a permanent wave curling rod about which a lock of hair is wound, the inner end 01": the rod being exposed beyond the first turn to heat said rod, of a protector of heat-insuating material enclosing the exposed end of the rod and insulating said end and preventing the latter from contacting with the scalp, said protector being separable from the lock of the lock of hair, and means to the rod and being removable from and cale of being applied to the rod while the of hair is curled thereon. 4,, A permanent wave appliance comprising a curling 'rod about which a lock orcurl of hair-is wound with the inner end of the rod exposed,a pad enclosing the curl, a heatingelement' enclosing the pad, in combinationwith a protector of heat-insulating material, said protector comprising a two-part member, one part having a socket portion to receive the exposed end of the rod and a flange portion extending part way around the socket member and the inthe form of a plate pivoted to the flange portion and provided with a recess to receive the rod when said part is in operative position.

In testimony whereof, I have signed my name to this specification.
